Hi Michal,

You can increase the character length for user_title field. Please refer below steps.

1) First you need to alter Users table by using below query

Alter table users

Alter column user_title nvarchar(100)

2) After this you need to update Custom_Edit table, as by default CRM created entry for every user field. Make sure value for column ColP_ColPropsId should be unique and it is as per your database. In my database it is 682 so you need to check at your database and use that only.

select * from Custom_Edits where ColP_Entity='Users' and ColP_ColName='user_title'

update Custom_Edits set ColP_EntrySize='100', ColP_DataSize='100' where ColP_Entity='Users' and

ColP_ColName='user_title' and ColP_ColPropsId=682

3) Once you are done with the same then perform metadata refresh.

Hope this helps!

Regards,
Dinesh
